Abstract
The invention is a method for deploying a trusted identity for a user issued by an issuer. The user has a user device configured to send a request for signature to an issuer device handled by the issuer. The request comprises a user public key allocated to the user. The issuer device is configured to compute an issuer signature by signing both the user's trusted identity and the user public key using an issuer private key allocated to the issuer. A block chain transaction containing the issuer signature is created and submitted to a Block Chain for transaction verification and storage.
